ASTM A36 U-Bolt Hot-Dip Galvanized in abrasive high-vibration Industry
ASTM A36 U-Bolt Specifications
Typical Applications
Advantages of A36 U-Bolts
✔ Cost-Effective : Cheaper than stainless steel (304/316) for moderate environments.
✔ Weldable : Suitable for fabrication projects.
✔ High Strength-to-Weight Ratio : Ideal for structural loads.
✔ Customizable : Bend radius, coating, and thread length adjustable.
Limitations
⚠ Corrosion Risk : Requires galvanizing/painting for outdoor/wet environments.
⚠ Not for Extreme Loads : For higher stress, upgrade to ASTM A307 Grade B or A193 B7 .
Polestar Metal Success Story: A36 U-Bolts in Heavy-Duty Industrial Applications
Project Overview
A leading heavy machinery manufacturer required high-strength, cost-effective fasteners to secure hydraulic pipelines in rugged mining equipment. The challenge was to prevent vibration-induced loosening while withstanding extreme mechanical stress and outdoor corrosion .
Solution: ASTM A36 U-Bolts
Material : ASTM A36 carbon steel (hot-dip galvanized)
Specs :
Diameter: 20mm (¾”)
Leg Length: 200mm (8″)
Inside Width: 100mm (4″)
Threads: UNC coarse (Grade 5.8)
Coating: 80µm hot-dip galvanized (ISO 1461)
Key Benefits Delivered
Durability: Withstood 50,000+ operating hours in abrasive, high-vibration environments.
Corrosion Resistance: Galvanizing prevented rust despite exposure to rain, dust, and chemicals .
Cost Efficiency: 30% cheaper than stainless steel (316) with comparable lifespan in this application.
Easy Installation: Pre-threaded design reduced assembly time by 20% .
Results
Zero failures reported over 3 years of continuous use.
Reduced maintenance costs by eliminating frequent fastener replacements.
Scaled to other projects , including construction crane rigging and off-road vehicle chassis .
